Abstract

Atomic Force microscope (AFM) is one of the powerful and useful tools in nanoscale science and
technologies with applications from surface characterization in material science, to the study of living
biological systems in their natural environment. AFM operate in three modes of contact, non-contact and
tapping mode. In this paper, by focusing on the development of a more comprehensive model of an AFM
micro-cantilever beam, considering the effects of mass and rotary inertia of the tip using Euler-Bernoulli
beam theory is considered. The comparison of the present results and the results of other investigators, which
has been done in case studies, generally shows a very good agreement. The results show that the effect of
mass and rotary inertia of the tip depending on its dimensions is important and should be considered. Finally,
the effects of cantilever inclination and tip height on the resonance frequencies are also examined.
